- Application filed January 1a, 1908. Serial No. 410,485.

geles, in the county of Los Angelesand State of California,have'invented new and useful Improvements in Magnifyi 1g Glasses, of

whlch the following is a speci tion.

This invention relates particularly to a novel form of .mounting for alens whereby I am enabled to make a combination of two lenses withoutincreasing the size of the complete mounting beyond what is usuallyemployed for one lens.

To this end my invention consists of a combination with an ordinarypocket magnifying' glass of amounting for a high power lens within thepivot of the usual or low power lens so that the space ordinarilyutillzed by the pivot may e occupied by the high power lens.

accomplish the above by means of the device described-herein andillustrated in the accompanying drawings in which:

F gure 1,1s a perspective view of mymagnifying glass in its openposition. Fig] I2,is. a longitudinal section of the same.

Referring to the drawings 5 designates a magnifying, lass case of theconstruction usually em oyed for pocket glasses and which may. -eprovided with a compass 6 and a securing ring 7 or any other attachmentwhich may be-desired.

. At the end of case 5 o posite ring 7 abearing sleeve 8 is mountedbetween the two side members 9 and 10 of case 5. Upon this bearingsleeve a frame 11 is rotatively mounted, according to the usualconstruction, and this frame carries a lens 12 which is of comparativelylow power.

- Sleeve 8 is provided on itslower end with a shoulder 13 upon which ahigh power lens 14 rests, the lens being laced within the sleeve withits upper en rojecting above the same. This high power ens is preferablyof the pyramidal form shownalthough it ma be of any other configurationwhich len s itself to placement inside of sleeve 8. A bushing 15 isadapted to fit tightly-within sleeve 8 and is provided with an internalbore 16 which is contracted at its end to form a circular shoulder 17which bears against the upper end of lens 14 and holes the same rigidlyin position. Bushing 15 is adapted to remain in place by being tightlyfitted but it may be cemented in or secured in any other manner which isdeemed desirable.

From the foregoing description it will be observed that my novel form ofmounting enses in one instrument without increasing the size of thecasein which they are mounted. This is on account of the fact that sleeve 8or the equivalent bearing for frame .11 must be of sufiicient size toprevent the frame from becoming loose thereon and to insure an evenrotation of the frame. I have utilized this space which is usually un-vnecessarily occupied by the bearing and therefore do not increase thesize of the magnifying glass as a Whole.

Having described my invention what I claim as new and de'sire to secureby Letters Patent is 1. A device of the class described, comprising apivotally mounted lens, and a second lens mounted within the pivot ofsaid first named lens.

2. A magnifying glass comprising a case, .a hollow pivot mounted in saidcase, a-lens mounted on saidpivot, a lens within said ermits thecombination of two magnifying pivot, and a bushing adapted to fit withinsaid, pivot and over "said lens.

, 3. A magnifying glass comprising a case, a sleeve mounted wlthin saidcase, a frame rotatively mounted on said sleeve, a lens mounted in saidframe, -a lens within said sleeve, and a bushing adapted to fitover saidlens and hold the. same in said sleeve.

In witness that I claim the.foregoing I have hereunto subscribed my namethis 4th day of January, 1908.
